LUBRICATEID HINGE.

Application filed March 22, 1919.

To all whom it may concern h Be it known that I, FnAnoisoo HERNAN- nnz YPEREZ, a citizen of the Republic of Cuba, residing at Habana, Cuba, haveinvented new and useful Improvements in Lubricated Hinges, of which thefollowing is a specification.

This invention relates to an improved form of hinge and aims to moreparticularly provide a device of this nature, which will require aminimum of attention and be very noiseless in operation.

Attention is invited to the attached sheet of drawings in which Figure 1is a side elevation of the entire hinge;

Fig. 2 is a section taken along the line A-B of Fig. 1;

Fig. 3 is a side elevation of the left hand, or weight carrying portionof the hinge;

Fig. 4 is a side elevation of the right hand or supporting portion ofthe hinge;

Fig. 5 illustrates the construction which renders my device noiselessand easy in operation; and

Figs. 6 and 7 are end views of the devices illustrated in Figs. 3 and 5.

In these drawings, 1 designates the leaf of the weight carrying portionof the hinge, and 2 the similar portion of the opposite half of thehinge, both of said leaves being provided with the usual counterboredopenings 3 for the reception of screws or other suitable securing means.The weight carrying, or left hand portion of the hinge is provided withlugs 4 and 5 formed with openings 6 positioned adjacent its upper andlower edges respectively.

The opposite leaf 2 has formed along its side edge a cylindrical casing6 provided with shoulder portions 7 adjacent its edges.

The casing 6 houses a rod 8 provided with a bore 9, such rod beingprovided with a shoulder portion 10 at its upper end. It will be notedthat the lugs 4 and 5 and the shoulder portion 10 are further providedwith an opening 11, as illustrated in Figs. 2, 6 and 7 The rod 8 hasformed in its lower face recesses 12, into which lugs 13 of a disk 14project, such disk 14 being further formed with an annular groove 15 inits lower face.

A cap 16 is positioned within the lower end of the casing 6 and projectsbeyond the same, as shown in Fig. 2, said cap being secured to thecasing by means of the screw Specification of Letters Patent.

Patented Apr. 27, 1920.

Serial No. 284,230.

' 17 The cap 16 is further formed with an annular groove 18 andinterposed between the lower face of the disk 14 and the upper face ofthe cap 16 is a second disk 19 formed with ball races in its upper andlower faces, housing ball bearings 20.

A headed pin 21 projects centrally through the disks 19 and 14 and therod 10, terminating at a plane above the upper face of the lug 4. Itwill be noted that the head 22 of such pin is provided with a cut outportion 23, adapted to receive a spike 24 projecting through theopenings 11 in the lug 4 and the rod 10, also that the rod is so formedas to permit of the existence of an annular space between its outer faceand the inner face of the cylindrical casing 6, such space being adaptedto receive any suitable lubricating material.

In operation it will now be seen that upon the leaf 2 being secured tothe jamb and the door being afiixed to the leaf 1, that downwardpressure will be exerted upon the lug 4, such lug bearing upon theshouldered portion of the rod 10, which turns therewith, said rodtransmitting in turn the weight to the disk 14 and the ball races 20,thus throwing all the weight upon the ball bearin s, resulting in easymotion of the door. t will be further noted that the disk 14 ispositively movable with the rod 10, which in turn is secured to the leaf1 by means of the opening 11 in the lug 4. The disk 19 revolves idlyabout the pin 21 and the cap 16 is fixed to the leaf 2 by means of thescrew 17 projecting through the cylindrical casing 6", thus renderingthe same immovable.

It will be understood that various modifications may be resorted to, asfor instance, the disk 14 being integral with the rod 10 and a secondopening 11 being provided through the lug 5 and shoulder of the cap 16,so that the hinge may be reversed.

Having now described my invention what I desire to claim is 1. A hingeincluding a pair of leaves, one of said leaves being provided with lugsadjacent its upper and lower edges, and the second leaf being formedwith a cylindrical casing adjacent one side edge, a rod secured to theupper lug to turn therewith, said rod projecting into and being spacedfrom the cylindrical casing, ball races positioned below the lower endof the rod, said ball races including a disk secured to the lower end ofthe rod to turn therewith, a base portion below said lower end, a diskpositioned be tween the first named disk and base portion, and bearingballs interposed between said latter disk, the base portion and thefirst named disk, and a pin, extending centrally through said upper lug,said rod and said disks.

2. A hinge including a pair of leaves, one of said leaves being providedwith lugs adjacent its upper and lower edges, a second leaf being formedwith a cylindrical casing adjacent its side edge, a rod secured to theupper of the lugs to turn therewith, such rod projecting into and beingspaced from the cylindrical casing, and a ball bearing 7 for the lowerend of said rod and in said caslng.

3. A hinge including a pair of leaves, one

of said leaves being provided with lugs adjacent its upper and loweredges, the second leafbeing formed with a cylindrical casing adjacentits side edge, a rod secured to the upper of the lugs to turn therewith,such rod projecting into and being spaced from the cylindrical casing,ball races positioned below the lower face of the rod, such ball racesincluding a disk secured to the lower face of the rod to turn therewith,a base portion below such lower face, a disk positioned between thefirst named disk and base por-t tion, and bearing balls interposedbetween such latter disk, the base portion and first named disk. 7
